Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electronic typewriter in which the size of printed characters can be selected, and in particular to automatic setting of line spacing at line breaks.

Conventional structure and problems Conventionally, typewriters, whether electronic or manual, could only print characters of a certain size, so it was necessary to make the characters, such as the headings of sentences, larger so that they would stand out. Also, it was impossible to print the entire text in a large size depending on the text to be printed.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks. It is possible to select the size of printed characters, and even when the vertical character size changes, the line spacing corresponding to the character size is changed to one line break. The purpose is to improve operability by making it possible to obtain results through operations.

Structure of the Invention The present invention provides at least a first switch for selecting the vertical character size of characters to be printed, and a second switch for selecting the space between lines when a line feed operation is performed.
a switch, a printing means for printing characters of a size corresponding to the first changeover switch, a keyboard section for inputting printed characters, and processing input from the keyboard section to control the printing means. The control unit is configured to control the space between lines when performing a line feed operation according to the first and second lines.
It is configured so that it is applied to the printing means as an output proportional to the setting value of the changeover switch,
The size of the characters can be changed, and the space between lines can be easily and freely determined according to the size of the characters.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a configuration diagram for explaining the present invention, and FIG.
The figure is a perspective view of an electronic typewriter according to an embodiment of the present invention. Reference numeral 1 denotes a main body, which includes a keyboard section 2 and the like. FIG. 3 is a detailed view of the keyboard section 2. As shown in FIG. 3 is a switch for selecting the horizontal character size, and 1, 2, and 3 times the size can be selected. On the other hand, 4 is a switch for selecting the character size in the vertical direction, and similarly to the above, 1, 2, and 3 times larger characters can be selected. 5 is a switch for selecting the space between lines, and 1, 1 1/2, or 2 lines can be selected. The keyboard section 2 has 45 character keys, a backspace 2a, a forward key 2b, a left margin set 2c, and a right margin set, in addition to a line feed key 6 that, when operated, causes a line break and returns the printed section to the left margin. 2d, tab set 2
It is provided with keys for e, tab clear 2f, margin release 2g, tab 2h, shift lock 2i, shift 2j, repeat 2k, space 2l, index 2m, and erase 2n, and perform operations corresponding to each key.

FIG. 4 is a block diagram of an embodiment of the present invention, in which the printing means 7 is specifically configured to print using a ballpoint pen, and the pen is moved left and right to move the ballpoint pen left and right. motor 9
A line feed motor 8 is used to move the attached paper vertically, and a pen vertical movement motor 10 is used to touch and release the pen from the paper to draw the desired character. The 8 to 10 motors are controlled by a control means 11. This control means 11 reads the line feed key 6, the horizontal character size changeover switch 3, the vertical character size changeover switch, the line spacing changeover switch 5, and other key inputs provided on the keyboard section 2, and operates according to the inputs. The printing unit 7 is configured to have the function of causing the printing unit 7 to perform the following.

Next, the operation of this embodiment will be explained using a flowchart of the main part of the control means 11 shown in FIG. Now, when you press the line feed operation button 6 after printing one line with this electronic typewriter, the control means 11 detects that a line feed operation has been performed in step 21, and first changes the value of the vertical character size changeover switch 4 in step 22. Read n. Next, in step 23, the value m of the line spacing switch 5 is read, and in step 24, l=2×m×n
shall be. Next, in steps 25 and 26, the character size is changed to half the vertical character size once, and the variable l is subtracted by 1, and in step 27, the variable l becomes 0.
Repeat steps 25 to 27 until the Finally, when l=0, the control means performs processing to return the pen to the left margin position in step 28.Furthermore, using the flowchart described above, the printing example shown in FIG. 6 will be explained in detail. explain. Figure 6a is an example of printing with horizontal character size X = 1, vertical character size m = 1, and line spacing n = 1. In this case, the steps in the flowchart in Figure 5.
24, l=2×1×1 and l=2, so the distance between the first and second lines is twice the amount x, which is half the vertical character size. Similarly, in Figure 6b, X=
1. Vertical character size m = 2, line spacing n
= 1, so l = 4, and the spacing between the first and second lines is 4x, and as shown in the figure, even if the vertical size m is changed, one line break search will separate the characters on the previous line and the current one. The characters you are writing will no longer overlap. In addition, Fig. 6c shows an example of printing when horizontal character size X = 1, vertical character size m = 1, and line spacing n = 2. A printing example is shown in which the vertical character size m=2 and the line spacing is 2. In this case, each l=
4, l=8, and the line spacing is 4x, 8x.

In this embodiment, the printing means is a ballpoint pen, but the present invention can also be applied to a multi-transfer method using a thermal head, etc., if the size of the characters is changed depending on the selection of the dots on the head. It is possible to have the following functions.

Effects of the Invention The present invention is an electronic typewriter in which it is possible to select at least the vertical size of printed characters and the space between lines at the time of line break, and the amount of line break space due to one line feed operation is adjusted according to the character size and line spacing. By configuring it to be proportional to the setting value, for example, even if the vertical font size increases, the inconvenience of having to perform line breaks several times is eliminated, making it an extremely easy-to-use electronic typewriter. can be provided.
